Dust production in the harsh environment of Sgr A* - MIRI/JWST observation of the O-rich asymptotic giant branch star IRS~3
F. Peißker, M. García Marín, A. Eckart +18
Studies of the interstellar medium (ISM) have frequently revealed signatures of the dust produced in the envelopes of asymptotic giant branch (AGB) stars, demonstrating a connectio…
XRISM Resolves the Circum-nuclear Environment of NGC 4945
Peter G. Boorman, Poshak Gandhi, Yoshihiro Ueda +31
Compton-thick Active Galactic Nuclei (AGN) represent one of the most elusive phases of massive black hole growth, yet are expected to contribute substantially to the Cosmic X-ray B…
MICONIC: The spatial relationship between star formation and the AGN in Centaurus A revealed by JWST/MIRI
O. C. Jones, M. L. Jones, D. Dicken +21
Centaurus A (Cen A), the nearest active radio galaxy, hosts a warped dust disc formed in a gas-rich merger. We present JWST/MIRI imaging in three filters, F560W, F770W, and F1130W,…
MICONIC: The multiphase circumnuclear region of Centaurus A as seen with JWST/MIRI MRS observations. I. Spectral inventory and properties of the warm molecular disk
L. Evangelista, P. Guillard, J. Martin +21
Supermassive black holes power Active Galactic Nuclei (AGN), injecting energy that regulates accretion and shapes host galaxies. We investigate the morphology, excitation, and kine…
MICONIC: JWST/MIRI-MRS reveals heavily reprocessed PAH emission in the circum-nuclear disc of Centaurus A
L. Pantoni, M. Baes, L. Decin +23
Polycyclic aromatic hydrocarbons (PAHs) are key dust components in galaxies and play a fundamental role in the physics of the interstellar medium (ISM), yet their response to AGN f…
A close look at the black hole masses and hot dusty toruses of the first quasars with MIRI-MRS
Sarah E. I. Bosman, Javier Ãlvarez-Márquez, Frederick B. Davies +29
The presence of supermassive black holes (SMBHs, ) at remains a puzzle. While their existence appears to require exotic formation or growth proce…
